It can be embarrassing to make mistakes with communication. For example, if you send an email without checking it, and later realize that it contained an error, you can end up looking sloppy and unprofessional.

But other communication mistakes can have more serious consequences. They can tarnish your reputation, upset clients, or even lead to lost revenue.

In this article, we'll look at 10 common communication mistakes, and we'll discuss what you can do to avoid them.

Mistake 1: Not Editing Your Work

Mistakes with spelling, tone, and grammar make you look careless. That's why it's essential to check all of your communications before you send them.

Don't rely on spell-checkers: they won't pick up words that are used incorrectly. Instead, proofread your work, and use a dictionary to look up any words that you're unsure about.

You may find it helpful to make a list of words and phrases that you find it hard to get right (such as "your/you're," "its/it's," or "affect/effect"). Store this close to hand.

It can be difficult to see errors in your own work, so consider asking a colleague to look over key documents before you distribute them. Alternatively, read your work aloud – this makes it easier to catch typos and tone errors. Then, give yourself time to reflect on your document, and to make any final changes.

Mistake 2: Delivering Bad News by Email

Would you announce layoffs to your team by email or IM? If you did, you could upset everyone!

Written communication channels don't allow you to soften difficult messages with nonverbal cues (such as body language  ), and they don't allow you to deal immediately with intense emotions.

If you need to deliver bad news, do this in person, and think carefully about how you can do it sensitively, so that you can convey your message but minimize long-term upset at the same time.

When you deliver a difficult message personally, you can pick up on signs that people may have misunderstood key parts of your message, or may have taken the information particularly badly. You can then take steps to clarify your message, or help people deal with the difficult news.

Mistake 3: Avoiding Difficult Conversations

At some point, you will need to give negative feedback. It's tempting to try to avoid these conversations, but this can cause further problems – in particular, you may let small problems grow into big ones.

Preparation is the key to handling difficult conversations. Learn to give clear, actionable feedback, and use tools such as the Situation – Behavior – Impact   technique to encourage your people to reflect on their behavior.

You may also want to role-play  your conversation first, so that you feel confident in both your words and your body language.

Mistake 4: Not Being Assertive

Assertiveness   is about stating what you need, while considering the wants and needs of others.

You may not always get your way when you're assertive, but you stand a better chance of getting it, or of reaching a compromise, because you've been clear about your needs. Use our Bite-Sized Training session on Assertiveness Skills to identify your needs, and to practice assertive communication.

Assertiveness also means saying "no" when you need to. Our article "'Yes' to the Person, 'No' to the Task"   explains how to turn down requests gently but assertively, while maintaining good relationships.


Assertiveness is not the same as aggression. When you're aggressive, you push to get your own way without thinking about other people's rights, wants, and needs.

Mistake 5: Reacting, Not Responding

Have you ever shouted at a colleague in frustration, or sent a terse reply to an email, without thinking your point through? If so, you're likely to have reacted emotionally, instead of responding calmly.

This kind of emotional reaction can damage your reputation. You may upset people with your strong emotions, and give the impression that you lack self-control and emotional intelligence  .

Read our article on managing your emotions at work   for tips on how to keep your reactions under control.

Mistake 6: Not Preparing Thoroughly

Poorly-prepared presentations, reports, or emails frustrate your audience and, over time, damage your reputation. This is why it's essential to prepare and plan your communications carefully.

First, set aside time to plan your communication thoroughly. Consider using tools like the Rhetorical Triangle   and Monroe's Motivating Sequence   to create a credible, intelligent, and compelling message that appeals to your audience's emotions, as well as to their intellects.

Leave time to proofread, to find images, and to check that documents are compatible with your audience's software. Then, if you are delivering a speech or a presentation, rehearse thoroughly, so that you are fluent and inspiring.

Mistake 7: Using a "One-Size-Fits-All" Approach to Communication

If you use a "one-size-fits-all" approach to communication, you may overlook people's different personalities, needs, and expectations. In fact, your communications need to address those differences as much as possible.

If you're preparing a presentation, make sure that you appreciate that people have different learning styles  , and that you cater for these. This means that everyone – from those who learn best by reading to those who prefer a more hands-on approach – can benefit from your session.

Mistake 8: Not Keeping an Open Mind When Meeting New People

Today's workplace is a melting pot of ethnicities, religions, ages, sexual orientations, and viewpoints. These differences create a rich tapestry of experiences and opinions that greatly enhance our lives.

However, it can be tempting to stereotype new colleagues or clients, or to make assumptions about them based on just a few pieces of information. This is especially true if you haven't had much time to get to know them well.

Assumptions inhibit open communication, because you don't consider the other person's own unique background, personality, and experience. Over time, this can jeopardize your relationship with them.

So, set time aside to listen   when you meet someone new. Give them space to talk about their viewpoints, and take time to absorb these.

Then, learn how to manage cultural differences  , so that you take each person's needs and expectations into consideration. If you often work with people from overseas, explore the idea of cultural intelligence  , so that you can start to adapt your behavior when you come across people from different cultures.


If you're new to working or managing internationally, read our managing around the world articles in the Team Management section to learn about working in different countries.

Mistake 9: Assuming That Your Message has Been Understood

Always take time to check that people have understood your message.

For example, when you send out an email, you could encourage people to respond with questions, or to reply if they haven't understood part of your message.

Or, if you've given a presentation, build in time for people to discuss your main points, or leave time for questions at the end.


To check that you've been understood correctly, use open questions that start with "how," "why," or "what." These encourage reflection, and will help your audience members to explain what they, personally, have taken from your communication.

Mistake 10: Accidentally Violating Others' Privacy

Have you ever forwarded a sensitive email to the wrong person, or sent an incorrect attachment? These kinds of errors can cause serious commercial problems, violate people's privacy, and lead to embarrassment and confusion.

To avoid these problems, write sensitive messages before you select the recipient, and then double check their email address. If your email program automatically fills in email addresses, you could switch this feature off, so that you must consciously choose the right recipient.

You may find it helpful to draft these emails in a word processing document or blank email, and then to paste the text into a new message. This way, you won't accidentally include any information from previous messages.

And, if you're sending a sensitive or confidential attachment, check that no "tracked changes" or comments can be found, and make sure that you're sending the right version.

Key Points

Everyone makes communication mistakes from time to time. However, you'll protect your reputation if you avoid the most common errors, which include not editing your work, accidentally violating people's privacy when forwarding emails, and not being assertive.

The key to good communication is to think about your audience's needs. Prepare each email, document, and presentation carefully, and give yourself time to check it.

Above all, remember that communication is a two-way process. Be ready for questions, and listen to what your audience has to say.

Over time, you'll find that good communication can greatly enhance your working relationships, and your job satisfaction.

    Hi Ayejunikanwa,
    Glad to hear that you liked the article and that it will help enhance your communication skills.

    Developing, or further enhancing, any skill takes regular attention and action to monitor the effectiveness and to make any adjustments. So, what sort of things will you focus on and how will you assess your progress?

    Hi TGale,
    Thanks for your comments, and your perspective on rhetorical questions.

    Certainly sounds like you do not appreciate that approach when listening to a speaker. Almost as if, and these are my words, 'tell me what you have to tell me and cut to the bottom line with your point'.

    That very direct approach can most certainly be useful. I definitely am a 'give me the bottom line' approach type of person, and sometimes become frustrated when they are telling me lots of detail or the story behind something!

    Yet, as a speaker/trainer/presenter, I do use rhetorical questions throughout my talks to engage the audience. I make sure I pause for a moment or two to let the question sink in and give the audience time to reflect on what their own answer might be.

    I see this as a difference between being talked at (which I hate!) and actually taking in what the person is saying. By engaging the audience with rhetorical questions, they can then compare/evaluate/assess their responses with the ideas that I am speaking about. All in view that they take something away that they will benefit from or do something different.

    Saying all that, there is a time and place for all the different approaches!

    What types of situations do you see rhetorical questions useful or not useful?

  • tgale wrote Over a month ago
    This type of article should always be in the forefront as a reminder to communicators that effective communication is a difficult skill and should be practiced to improve. While communication may be referred to as a tool, it is the craftsman that controls the quality of output.

    One of my current pet peeves with contemporary communication fads is what I call the "auto-rhetorical" question. It offends me that the speaker is so bold to assume what questions I should be asking in order for him to make a point. It shows disrespect for the listener/reader and undermines the engagement necessary for productive interaction. Just say what you have to say and let the listener ask necessary questions.

    Have I been a little overreactive on this? Yes I have. Are there better ways to make point? I believe there are.

    I would love to start an anti-autorhetoric campaign. Any followers?

    This is a great article that sums up some very common mistakes that many of us have done. I know I certainly am guilt of a few of them on the list!!

    Whether it is sending an email to the wrong recipient or forwarding an attachment that should not have been forwarded or any of the others, this article provides great advice as to how to avoid communication mistakes.

    Reacting emotionally to a person is one thing, it is another thing when you actually write out the anger in words ... because the words remain for the person to re-read again, and again, and again!

    I'm curious, what mistakes have you made and how did you deal with them to rectify the situation?
